VN is advised to promote the carbon credit market in the refrigeration and air-conditioning sector as one way to protect the ozone layer.

Vietnam has begun to develop carbon pricing instruments and an emission trading system (ETS) to incentivise firms to reduce their greenhouse gas (GHG) emissions and move towards the use of clean energy.

Many countries are now adopting emissions trading systems as a means to reduce annual emissions. Vietnamese firms, thus, must understand and participate in this market.
